2 Claims. 1

This invention appertains to concrete, terrazzo, magnesium oxy-chloridecomposition, and like floors or surfaces, and more particularly to anovel method of laying such surfaces and to a novel screed striptherefor.

In laying concrete and like surfaces, it is was tomary to use screedstrips to facilitate the leveling of the outer face of such surface andto thereafter remove the strips and finish the surface.

It is therefore one of the primary objects of my present invention toprovide pre-cast screed strips formed of the same, or substantially thesame material as the floor or other surface and to leave such strippermanently in position, whereby the necessity of removing the strips iseliminated and whereby such strips can be advantageously used as anornamentation for the surface, it being understood that the strips canbe made in various colors, if so desired.

Another salient object of my invention is to provide means whereby thescreed strips can be effectively used in the laying of concrete orsimilar shuffle board or other playing courts, the strips functioning asdivision members for the numbered zones as well as leveling strips, thenovel construction of the strips permitting the outer face of the courtto be readily finished or sanded, the strips also functioning to provideshrinkage lines to prevent the forming of irregular cracks in thefinished surface.

A further object of my invention is to provide a pre-cast screed stripor other ornamental member for use in concrete or like floors, whichembodies a resilient core on which is molded the concrete body portionwhereby a resilient or flexible strip will be had which can beeffectively handled and shipped.

A further important object of my invention is to provide novel means forinsuring the proper adhesion of the concrete or like moldable body onthe resilient core, whereby danger of cracking or loosening of the bodyon the core is avoided.

With these and other objectsin view, the invention consists in the novelconstruction, arrangement, and formation of parts, as will behereinafter more specifically described, claimed, and illustrated in theaccompanying drawings, which drawings:

Figure 1 is a detail vertical sectional view through a fragment of ashuflleboard court and showing one step in the laying of said court, thesection being taken substantially on the line l-l of Figure 2.

Figure 2 is a fragmentary top plan View of the court showing one step inthe method of making the court, the view being on a smaller scale thanFigure 1.

Figure 3 is a view similar to Figure 1, and showing a further step inthe making of the court, the

section being taken substantially on the line 3-3 of Figure 4.

Figure 4 is a fragmentary top plan view of a shuffieboard court showingthe additional step in the laying of the court.

Figure 5 is a view similar to Figure 3 and illustrating the method oflaying a surface, such as a shufileboard court on an existing floor orother surface which is out of level.

Figure 6 is an enlarged fragmentary detail perspective view showing theinner resilient core of one of the screed strips and illustrating themethod of treating such core to facilitate the bonding of the concreteor other moldable substance thereon to form a screed strip or otherdesired ornamentation.

Figure '7 is a fragmentary detail perspective: view showing one of thestrips afterthe making thereof.

Figure 8 is a top plan view partly in section showing the methodutilized for making precast numbers or other ornamental members, and

Figure 9 is an enlarged detail transverse sectional view taken on theline 9 9 of Figure 8, looking in the direction of the arrows.

Referring to the drawings in detail, wherei similar reference charactersdesignate corresponding parts throughout the several views, the numeralIll indicates a base or floor on which the shufiieboard court or othersurface is to be laid. This base In can either be an existing surface,such as wood, concrete, steel, marble, brick,

stone, etc, or can be newly laid concrete or the like.

After the base ID has hardened (in case of a newly laid floor), theupper surface thereof is treated with a. bonding coat H for sealing theupper surface thereof and for facilitating the bonding or the adherencethereto of the finishing surface which is to be laid thereon. After thebonding coat hasbeen poured, sprayed or otherwise placed on the uppersurface of the base, the division screed strips l2 are placed inposition on the bonding coat and these strips are secured to the base 10by said bonding coat, or by a thin mixture of Portland cement in water,or a mixture of Portland cement and finely screened sand and water. Itis to be understood at this time that the screed strips l2 are of anexact same height so that the same can be used to level the finishingcoat l3 for the base l0. Likewise, any other ornamentation to be used isalso placed upon the base 10 and secured thereto by the bonding coat. Inthe laying of shuffle board courts, pre-cast numbers M are utilized andthese numbers are formed in the same novel manner as the screed stripsl2. The method of forming the screed strips will now be described andthe screed strips themselves form an important feature of thisinvention. 7 v

In forming the screed strips I2, I utilize a resilient flexible innercore [5 which is preferably formed from a desired length of wood ordowel. A particular type of wood is utilized which possesses the desiredresiliency, such as maple or birch.

The outer face of the core I5 is provided with a bonding coat I6 andthis bondin coat l6 can be of the same nature as the bondin coat Il,'pre viously mentioned. While the bonding coat I6 is still in itsplastic or tacky stage, granules 'I'i are placed thereon. The granulescan' be of anydesired material or substance and the bonding coatfunctions to firmly hold the same in place. Thegranules are preferablyof natural "stone or ceramic materials, such as crushed brick or firedclay as used commercially for roofing (granules; or any other suchgranules can be used. It is highly desirable that these granules be ofapproximately the same size, so that 'they'will form a single uniformlayer in 'con'tactw'ith the plastic adhesive or bonding coat l6.Actually, the individual granules are-fixed to the cores l5 byattachment of their lower 'halve's or sections only. permitting theirupper halves to remain receptiveto the cement or like material to bebonded thereto.

After the forming of the cores 15 with the granules I! thereon, the sameare placed in suitable forms and the'body'por'tions IE or the strips arecast on the cores. The body portion Iii can be formed from the samematerial as the surface (3, it being understood, however, that anydesired coloring material can be added to the concrete or like mixture.

After the body H! has hardened, an elongated flexible screed strip willbe had which can be readily handled or shipped without undue dan ger ofbreakage.

In forming numbers or other ornamental devices, I utilize the samemethod "as "employed in making the screed strips. For instance, in making the number 8 (see Figures -8 and 9'), l utilize wooden cores 19 witha bonding coat and gram ules 2t and these cores are arranged so as to'ef the finishing surface I3 is poured in place. After the pouring ofthe concrete or like finishing face, the same "is leveled in the usualmanner, and the screed strips I2 and the numbers H are utilized tofacilitate such leveling. After the finishing surface has hardened, thesame can be polished or otherwise treated, and it is obvious that as thescreed strips 12 and the numbers 14 are formed substantially from thesame material as the surface IS, the entire coat can be readily andeasily finished.

While I have shown the screed strips l2 and numbers 14 for ashufiieboard court, it is to be understood that the screed strips can beutilized in laying any desired floor or other surface.

Where a surface is to be laid on an existing floor, means is providedfor leveling the upper face of this fioor, when necessary. In Figure 5 Ihaveshown a fragment of an existing floor 22 and the upper face of thefloor is first provided with a bonding coat, after which a thin layer ofconcrete, or the like, 23 is applied and held in place by said bondingcoat, and this concrete or like layer has its upper surface leveledsmooth and-111a horizontal plane. The upper surface of the leveling coat(after hardening) may be sprovide'd witha 'bonding'coat 24. The screedstrips i2 and the numbers M are placed on this bonding-coat 24, andafter the strips andnumbers have been placed in position, then thefinishing surface '25 can be poured in .placepver the bonding coat.

From the foregoing description, it can be seen that I have provided anovel and efficient means for laying concrete, terrazzo, or like floorsand other surfaces.

Changes in details may be made without departing from the spirit or thescope of my invention, but what I claim as new -is:

'1. A pre-cast screed strip for use in laying co'n crete, terrazzo, andlike floors and surfaces, com prising a resilient longitudinallyextending core, granules secured to said core throughout the lengththereof, and a concrete or like body cast on said core and connectedtherewith by said granules.

2. A vpre cast screed strip or ornament for use 'in laying concrete,terrazzo, and like floors or surfaces comprising a longitudinallyextending resilient core, a bonding and sealing coat on said core,granules secured to thec'ore by said bonding coat and extending the fulllength thereof, and a concrete or like body'cast on said core andconnected therewith by said granules.
